A recent commit restored the original (and still documented) semantics
for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address
is considered invalid unless an address is provided by firmware.
This specifically means that this flag must only be set for devices with
invalid addresses, but the Broadcom BCM4377 driver has so far been
setting this flag unconditionally.
Fortunately the driver already checks for invalid addresses during setup
and sets the HCI_QUIRK_INVALID_BDADDR flag, which can simply be replaced
with HCI_QUIRK_USE_BDADDR_PROPERTY to indicate that the default address
is invalid but can be overridden by firmware (long term, this should
probably just always be allowed).

bcm4378 and bcm4387 claim to support LE Coded PHY but fail to pair
(reliably) with BLE devices if it is enabled.
On bcm4378 pairing usually succeeds after 2-3 tries. On bcm4387
pairing appears to be completely broken.

Broadcom BCM4377/4378/4387 are dual WiFi/Bluetooth boards found in Apple
machines. This driver adds support for the Bluetooth function which
exposes a shared memory IPC protocol over PCIe to tunnel HCI traffic.
